SPEGIFICATION forming para of Lettefsrant No. 729,367, .dated May 26, 1903.

Application filed September 20, 1902. Serial No. 24.188. (No model.)

To all whom t may concern,.-

Be it known that we, ALVAH F. LENT, of 34 Ward street, and JOEL W. HATT, of .40 Lawrence street, Newark, Essex county, New

Jersey, citizens of the United States,have in-VY vented certain new and useful Improvements in Tapping-Brings, fully describedand represented in the following speciiication and the accompanying drawin gs, form in g a part of the same.

The object of the present-invention is to" furnish an improved construction for the combined bung and cock which is sometimes applied to beer-kegs to facilitate the drawing of beer therefrom.

The construction relates to that class'inV which is termed herein the air-supply fix-- ture, is formed with a screw-thread to t asuitable socket upon the outer end of the passage from the bung and with handles for turning the fixture, with ai stufing-box upon the.

outer end to packthe joint with the draftpipe, and with an air-supply nozzle upon the side to which a hose may be attached for forcing air into the keg to discharge its contents.

The invention will be understood by reference to the annexed drawings, in which' Figure lis a section of the bung with part of the side of the keg and the draft-pipe and air-supply fixture applied to the bung. Fig. 2 is a section of the bung with the cock turned to close the passage. Fig. 3 is a plan of the top of the bung. Fig. et a4 plan of the bottom, and Fig. 5 shows the retarring-stopper.

a designates the body of .the bung, provided with the usual thread to screw into the keg h.

c is a plug inserted'diagonally inthe bung and formed with a diagonal passage d, which extends to the interior of the keg and when the plug is suitably turned stands inline with the passage d', which extends to the outside of the bun g, the two passages forming a straight channel from the exterior of the bung to the interior of the keg through which the usual draft-pipe finay be freely inserted. The plug and passage are so arranged that when the plug is turned a little more than a quarterrevolution, as shown in Fig. 2, it closes the passage and retains the liquid and gas inthe keg during transportation.

The top of the passage d' is provided with a threaded socketp, having a seat n, with packing j in the bottom, and the detachable air-supply fixture e is provided with threaded shank e', fitted to suoli socket, and with handles of to screw it down upon the pa'okingj.

YThe air-supply fixture furnishes anI extension of thepassage d and is provided on top with a stuffing-box cap h, screwed upon an annular packing 'L'. The air-supply xturev is screwed into the bung before-V the plug c is turned to open the passage, and the draft-pipe is also inserted through the packing c" into` the fix-v ture, which stands in line with the passage.

The escape of gas around the draft-pipe is thus prevented by the packing 1l when the .plug is turned to push the draft-pipe into the keg,- the usual cock at the upper end. of the draft-pipe preventing escape -in that direction. The draft-pipe is thus inserted in the 'keg without anyloss of pressure, and the connection can be made from the cock upon the draftpipe to the beer-tap before such cock is opened.

The supply-fixture e is provided with a nozthe liquid from the keg, the passage from the nozzle g being extended downwardly to the end of the shank e, where the air escapes into the passage d and passes into the keg around the draft-pipe. The air-supply fixture, which is thus connected detachably with the bung l by the shank e', serves the double function of introducing the air under pressure Vto the keg, while it makes a tight joint between the draftpipe and the keg beforethe plug 'c is opened and is removable from the bung when the passage is closed to avoid any projection from the exterior of the keg in transit. Awrench 7a is shown fitted to a suitable socket upon the outer end of the plug to turn the saine at pleasure, and two stops Z are formed in the gzle g at one side to receive a hose Vvg forsup- A .plying the air under pressure to discharge IOO end of the bung, with a pin m upon the plug to limit the rotation of the plug when turned bythe wrench and thus set the passages (l and d' in line When required.

With the combined bung and plug cocks heretofore used it has been considered impossible to ret-ar the barrel internally without removing the bung, butwe are enabled to protect the passages in our construction from the introduction of the tar, so that the bung and cock may be left in the barrel when it is retarred. This protection We secure by the insertion of a straight Wooden stopper s tightly in the passages (l d", which are set in line for such purpose when it is desired to retar the barrel. This wooden stopperexeludes the tar from both passages, so that when the barrel has been ret-arred the stopper may be withdrawn and the entire fixture restored toits normal condition. The chief part of our invention is the provision of the bung with the diagonal plug, the passages d (l, formed through the bung and plug, and the passage df, having the threaded socket upon its outer end, with the detachable air-supply fixture constructed not only to supply air, but to form a tight j ointwith the draft-pipe when inserted in the same before opening the passage to the y barrel.

inga draft-pipe; but our construction dilfers from others in the particular combination and arrangement with the passage d' in the bung of the detachable air-supply fixture shown and described herein. y

Having thus set forth the nature of the invention, what is claimed herein is The beer draft-fixture for kegs comprising the bung a and the diagonal plug c having the passages (l and d' in line through the same, and the threaded socket p having the seats n with paekingj thereon, in combination with the air-supply fixture e having shank e fitted to the socket p and the paekingj, and having handles r as set forth, and provided upon the top with the stufng-box cap h and packing 1L', and upon the side with the airsupply pipe g having its internal passage eX- tended downwardly to the end of the shank ef, the fixture operating for introducing the draft-pipe into the keg and supplying air to the same, and being detachable from the keg during the transportation of the latter.

In testimony whereof we have hereunto set our hands in the presence of two subscribing Witnesses.
